This study includes solvent extraction and electrowinning of copper from leaching process. The Taguchi method was used to determine the optimum conditions for solvent extraction process of copper ore in sulfuric acid solution. The experimental p... see more

The selection of strains isolated from technogenically altered ecotopes and resistant to contamination, capable of metabolizing a wide range of pollutants is a task highly relevant for creation of new methods for environmental purification. Sulphur-reduci... see more

Single-step ultrasound-assisted synthesis of Copper Zinc Tin Sulfide nanoparticles (CZTS) has been studied at two different frequencies. While the effects of frequency on the particle size of the CZTS nanoparticles were insignificant, a noticeable change ... see more

This research explored the performance of a fixed-bed anaerobic bioreactor system (FBR) using sulfate-reducing bacteria (SRB) from the sediment of Sikidang Crater in Indonesia. Indonesian natural zeolite was used as an inert medium in this bioreactor syst... see more

The processes of obtaining semiconductive and electrically conductive layers of mixed copper chalcogenides CuxS–CuyTe by the sorption-diffusion method on polyamide 6 using solutions of potassium and sodium telluropentathionates, K2TeS4O6 and Na2TeS4O6, an... see more

The processes of formation of electrically conductive layers of copper sulfides CuxS by the sorption-diffusion method on polypropylene (PP) using molten sulfur as sulfurizing agent was investigated. The amount of sorbed sulfur increased with the increase ... see more

The Ag-Cu-S layer formed on PE demonstrated a wide variation in thickness. The cross-section showed the average thickness of sulfide layers on PE increase from 1.9 mm to 5.6 mm with the increase in the sulfurization time and from 1.9 mm to ... see more

Salobo plant processes a gold and copper sulfide ore. The flotation process comprises the rougher, cleaner, and scavenger stages. Concentrate from the rougher and scavenger stages goes through a regrinding process before being fed into the cleaner stage. ... see more

Large-scale Cu2S tetradecahedrons microcrystals and sheet-like Cu2S nanocrystals were synthesized by employing a hydrothermal synthesis (HS) method and wet chemistry method (WCM), respectively. The morphology of a-Cu2S powders prepared by the HS method is... see more
